LEMAN cutting wheels Abrasive Cutting - Wheel

1, wheel no cracks no damage. 

2, the wheel must be in good condition no cracks, no damage. Before installation should be visually checked and found crack damage, is strictly prohibited. 

3, prohibit the use of damp, stainless steel cutting discs‍ cold wheel. 

4, use rubber binder wheel does not allow contact with oil, resin bond grinding wheel is not allowed contact with alkali substances, otherwise it will reduce the strength of the wheel. 

5, are not allowed to use the store over the rhythm of wheel. Such wheel will deteriorate, the use of very dangerous. 

6, resin bonded grinding wheel is generally one year, rubber bonded grinding wheel is generally two years, subject to the manufacturer's instructions. 

7, material cutting machine is prohibited under the magnesium alloy wheel. 

8, replacement wheel, mill workers should diamond concrete‍ comply with the general safety procedures. Wheel of plywood to fit, generally not less than one-third wheel diameter.

abrasive cutting wheel Metal bond diamond wheel

A diamond or cubic boron nitride (CBN) abrasive grinding wheel metal cutting wheels produced, because of its excellent grinding performance, have been widely used in various aspects of grinding. Diamond grinding wheel is carbide, glass, ceramics, gems high brittle materials effects tools. In recent years, with the rapid development of high-speed grinding and ultra-precision grinding technology, the wheel has put forward higher requirements, ceramic and resin bonded grinding wheels can not meet the needs of production, metal bonded grinding wheel because it tile cutting wheels‍ combines strength high, forming a good, long life and other significant features which have been widely used in production.

LEMAN cutting wheels Sintered metal bonded grinding wheel

Mostly bronze and other metals as a binding agent, with a high temperature sintering method, which combines high strength, good formability, high temperature, thermal tile cutting wheels‍ conductivity and good wear resistance, long life, can withstand greater loads. Wheel in the sintering process because there is inevitably shrink and deformation, so before shaping the grinding wheel must be used, but it is rather difficult dresser. Currently used in the production of plastic wheel to roll in the dressing method not only time-consuming, but the process of trimming off the diamond particles are more wheel dressing itself consumes large, low-shaping accuracy. 

In recent years, scholars from various countries metal cutting wheels have been carrying out a study of the application of special processing method of finishing work metal bond diamond wheel, mainly electrolytic dressing, French dressing and composite trim EDM method. Electrolytic dressing method is fast, but shaping accuracy is not high; high precision EDM shaping trimming method, can be either plastic dressing, but shaping slower; composite trimming method spark composite electrolytic dressing, mechanical chemical compound trimming method etc., dressing better, but the system is more complex, and therefore sintered diamond wheel trim problem still has not been solved. Further, since the grinding wheel determines the manufacturing process is a random surface topography, geometry of the abrasive grains, the distribution and the height of the cutting edge which is inconsistent, so that only a few high cutting edge to cut the workpiece, the cutting wheels‍ grinding limit further improve the quality of grinding and grinding efficiency.

tile cutting wheels Plated metal diamond wheel

Advantages electroplated diamond grinding wheel: ① plating process is simple, low investment, easy manufacturing; ② without dressing, easy to use; ③ monolayer structure construction cutting blades‍ determines it can achieve high operating speed, the current foreign high as 250 ~ 300m / s; ④ Although only a single layer of diamond, but there is still sufficient life; ⑤ for higher precision roller and the grinding wheel, is the only method of manufacturing electroplating. It is because of these advantages, plating wheel occupy undisputed dominance in high-speed, ultra-high speed grinding. Electroplated diamond grinding wheel defects: In conjunction with the surface of the metal coating and the substrate does not exist a strong abrasive chemical metallurgical combine, in fact, just being mechanically entrapped abrasive embedded in the coating metal, and thus a small holding force, the diamond particles in the load efficient grinding heavy shedding (or plating flaking) and lead to an overall failure; gripping force to increase the coating thickness must be increased, the result is highly abrasive and bare chip space is reduced, the wheel prone to clogging, cooling effect is poor, the surface prone to burns. Currently electroplated grinding wheel manufacturing has not been achieved by the optimized processing conditions required to flat cutting disc‍ design the best wheel topography, these inherent drawbacks of a single-layer electroplated diamond grinding wheel is bound to greatly limits its application in the grinding efficiency....

abrasive cutting wheel Monolayer brazed diamond grinding wheel

In order to give full play to the role of diamonds, to try to increase the bond and diamond holding force, improve the bonding strength of the wheel. High temperature cutting wheels‍ brazing single grinding wheel to overcome the shortcomings of the electroplated grinding wheel, the diamond can be achieved, metallurgical chemical binders, metal bonding between the three substrates having a high bonding strength, the thickness of the bonding layer will remain in the mill only grain height can be 20% to 30% efficiency at high load high speed grinding abrasive firmly hold on so bare brazing highly abrasive grinding wheels up to 70% to 80%, thus increasing the chip space, wheel clogging, use abrasive more fully. In the electroplated grinding wheel under the same processing conditions, a single layer of high temperature brazing superhard abrasive wheel grinding force, the power consumption, lower the temperature of the grinding means construction cutting blades‍ to achieve higher operating speeds, which 300 ~ 500m / s more ultra-high speed grinding has special significance.
